How Do People Afford Houses?
Most people afford houses through a combination of a saved deposit, a mortgage based on their income, and often a second income from buying jointly. Behind the scenes, help from family, government schemes and years of steady saving frequently bridge the gap between a salary and a property price that can feel out of reach.
There is no single trick, and it rarely comes down to a huge income alone. In this insight we take an honest look at how the numbers actually work, from deposits and income multiples to joint buyers, gifts and schemes, plus practical ways to close the gap.

- Typical mortgage
- ~4–4.5x income
- Common deposit

- Big lever
- Buying jointly
- Frequent help
- Gifted deposits
Try the reality check. Enter a price, the deposit you've saved and your (joint) income to see the three numbers that actually decide it — your deposit percentage, the income multiple you'd need to borrow, and the rough monthly payment.
🔑 Can you afford it? · live
To buy a £250,000 home with a £15,000 deposit you’d borrow £235,000 — that’s 6.7× your £35,000 income. Most lenders cap borrowing near 4.5× income (~£157,500), so you’d likely need a bigger deposit, more income, or a cheaper home.
A rough guide, not a mortgage decision. Lenders assess your full finances (outgoings, credit, job type) and multiples/rates vary. The payment assumes a 25-year repayment term at the rate you set.
Key Takeaways
- Affordability usually comes from three things together: a deposit, a mortgage of roughly 4–4.5 times income, and often a second income.
- Joint buying is one of the biggest levers, because lenders can consider two incomes when working out how much to lend.
- Gifted deposits from family and government schemes for first-time buyers help many people bridge the gap to their first home.
- Your credit profile and existing debts directly affect how much you can borrow, so both are worth managing before you apply.

How much a lender will offer you depends heavily on your credit history — the same salary can support very different loan sizes depending on what your file shows.
Checking your report before you apply lets you fix errors and clear small debts that quietly reduce how much you can borrow toward a home.

The Deposit: Where It Comes From
A deposit is your own contribution to the price, with the mortgage covering the rest. Many first-time buyers put down between 5% and 20%. A larger deposit means a lower loan-to-value, which improves your mortgage rate, so people save for as long as they can to push the deposit higher.
Deposits are built in several ways: years of steady saving, using a Lifetime ISA or other savings, downsizing or selling an existing property, and very often a gift or loan from family. There is no shame in any of these routes, and combining them is normal.
Income Multiples: How Much You Can Borrow
Lenders generally offer around four to four and a half times your annual income, though this varies with your circumstances, deposit and the lender's own affordability rules. Some lenders go higher for certain professions or higher earners.
Crucially, the figure is not just about salary. Lenders assess affordability by looking at your outgoings, existing debts and financial commitments too, so reducing debt and monthly commitments can increase how much they will lend. You can get a realistic estimate with a mortgage affordability calculator and see the monthly cost with a mortgage calculator before you start viewing.
Buying Jointly: The Biggest Lever
One of the main reasons houses are affordable is that many are bought by two people. When you buy jointly, lenders can take both incomes into account, which can substantially increase the mortgage available. Two people also share the deposit saving and the monthly repayments.
Joint buyers are not only couples. Friends, siblings and family members buy together too. It is worth understanding the ownership options, such as freehold and leasehold and how you hold the property between you, before committing, so take legal advice on joint ownership arrangements.
Family Help and Gifted Deposits
A large share of first-time buyers receive help from family, often called the "bank of mum and dad." This typically takes the form of a gifted deposit, where money is given (not lent) to boost the deposit. Lenders usually require a letter confirming the gift is not repayable and does not give the giver a stake in the property.
Some families help in other ways, such as acting as a guarantor or using specialist family-assisted mortgage products. These arrangements have legal and financial implications for everyone involved, so proper advice matters.
Government Schemes and Other Routes
Various government-backed schemes exist from time to time to help buyers, particularly first-timers, with smaller deposits or shared ownership of a property. Shared ownership, for example, lets you buy a share of a home and pay rent on the rest, lowering the upfront requirement. Because scheme availability and rules change, always check the current official position before relying on one.
Beyond schemes, people bridge the gap by buying in cheaper areas, buying a smaller first home to get on the ladder, or extending the mortgage term to reduce monthly payments. Our first-time buyer guide and pay vs house prices data help you see how salaries and prices compare across the country.
Practical Ways to Bridge the Gap
- Boost your deposit through consistent saving and tax-efficient savings products.
- Reduce existing debt so lenders will offer more and your rate improves.
- Buy jointly to combine incomes and share the load.
- Consider location and property type — a first step on the ladder need not be your forever home.
- Protect your credit file, since it directly shapes how much you can borrow.
Frequently Asked Questions
How much deposit do I actually need to buy a house?
Many first-time buyers put down 5% to 20% of the price. A bigger deposit lowers your loan-to-value, which usually means a better interest rate, so save as much as is realistic without leaving yourself with no cash buffer.
How much can I borrow on my salary?
As a rough guide, lenders offer around four to four and a half times income, but the real figure depends on your deposit, outgoings, existing debts and credit history. An affordability calculator gives a more personal estimate than a simple multiple.
Do most people get help from family to buy a home?
A significant proportion of first-time buyers receive some family help, often a gifted deposit. It is very common, but far from universal — many people also buy through years of saving, joint incomes and buying within their means.
Is it easier to afford a house with two people?
Generally yes. Buying jointly lets lenders consider two incomes, which can increase the mortgage available, and it splits the deposit and monthly costs. This is one of the main reasons many homes are bought by couples or pairs of buyers.
